Doorstep bets phone sensors prove deliveries reached the door; $8M seed follows

Doorstep sells precision indoor tracking for last-mile delivery: software that runs on a courier's smartphone, integrates into existing delivery apps, and uses built-in phone sensors to record when a driver enters a building, takes an elevator or stairs, reaches a floor and completes a drop at the doorstep.

That the phone in a driver's pocket can prove the last 100 feet — replacing cameras, lockers and blurry photos with indoor tracking that platforms will pay for

An $8 million seed announced Sep 25, 2025, led by Canaan Partners with Antler, Cercano Management, Cassius and Kleiner Perkins scout Sean Henry; earlier support from the Antler accelerator and an Innovate Carolina student-venture grant.

Shashwat Murarka kept losing food orders and giving confused couriers step-by-step directions through his apartment building, so he studied the delivery supply chain, ran deliveries himself, timed drivers with a stopwatch and followed couriers into buildings to watch what the apps showed. He connected on LinkedIn with Sheel Patel, a UNC computer science student who had delivered for DoorDash and had the same frustration; Patel built the sensor-fusion prototype during his senior year with help from an Innovate Carolina grant. When Murarka moved to New York, he slept in the office of the Antler accelerator he had joined.

On Sep 25, 2025, Doorstep announced an $8 million seed led by Canaan Partners, with Antler, Cercano Management, Cassius and Kleiner Perkins scout Sean Henry participating, and Canaan general partner Hrach Simonian joining the board. The company said the software tracked movement inside buildings with sub-5m accuracy, that it was live across U.S. states, and that the capital would move the technology from pilot to full production. It declined to name customers but told TechCrunch it had talked with every top on-demand delivery company; by March 2026 the startup had ten people, and Forbes had put both founders on its 30 Under 30 list.

Doorstep is still in its growth phase: as of March 2026 it had no named marquee customer, but it was live across U.S. states, moving from pilots to full production, hiring in engineering and product, and fielding early interest from emergency services in using indoor tracking to locate people inside buildings.

The blind spot is where the value is: GPS works outside but fails inside buildings, and that is precisely where false refunds, failed deliveries and blurry proof-of-delivery photos come from.

The zero-hardware constraint made adoption realistic: the phone is already everywhere, so platforms get indoor verification without installing anything in buildings.

The data is designed to be trusted: no driver or user information is collected, and the verifiable timeline lets support teams resolve refunds automatically instead of arguing over photos.

Traction evidence is concrete: TechCrunch coverage of the round, a Forbes 30 Under 30 nod for both founders, and a claim of nationwide deployment supporting over 160 million doorsteps.

Find where the incumbent technology fails: GPS stops at the building door, so Doorstep sold proof of the last 100 feet using the phone already in the driver's hand — no hardware to install

As of March 17, 2026, Doorstep is a ten-person New York company moving from pilots to full production after its $8 million Canaan-led seed. It is live across U.S. states and says it can support more than 160 million doorsteps; Canaan partner Hrach Simonian sits on the board. The company still declines to name customers, so demand evidence is indirect: it told TechCrunch it had talked with every top on-demand delivery company, and UNC reports emergency services are exploring the indoor-location technology. The test is converting those conversations into named, renewing contracts.
